The murder of a well-known author's son in
Mexico's out-of-control drug war has become a key catalyst for
organizing nationwide protests set for Wednesday against crime and
violence.

Juan Francisco Sicilia, 24, was found dead in a car along with
four close friends on March 28 near Cuernavaca, 90 kilometers (55
miles) south of Mexico City. Police also found the bodies of two close
relatives of one of Sicilia's slain friends nearby.

Police said they found a message in the car signed CDG -- the initials of the Gulf drug cartel organization.
